The Early History of Data Networks by Gerard J. Holzmann and Bjorn Pehrson.
Thanks — added to my “to read” list, too.
You’d enjoy “The Victorian Internet” — the history of the telegraph in a short form. I also liked “A Thread Across the Ocean: The Heroic Story of the Transatlantic Cable” by John Steele Gordon.
Both of these weave the business history with the technology history. It’s always fascinating learning about the inventors and the people who made fortunes — and they are often not the same people.
